This is such a fascinating (and disturbing) situation. And quite mysterious. High frequency ultrasound is used routinely in medicine and has never been shown to change brain tissue. Infrasound has some effect on tissue but its probably overstated. (the infamous 'brown note' [1]. Other sonic weapons rely on volume/amplitude. None of this seems to be the case here. Another really interesting point is the description of the hyper localized nature of the sound -- present in one part of the room and not another. Its really hard to localize a sound signal, as anyone who has worked with parabolic speakers can attest. Yes, there can be focal points, but the sound definitely drifts out to the surrounding areas to a significant degree. One example of hyperlocalized sound perception is Lamont Young's 'Dream House' installation in NYC [2] Although not captured in video documentation, there are distinct and significant microtonal shifts that are easily perceptible as you move through the space caused by standing waves produced through the interaction of the tone generators and the architecture. But this happens within the context of a loud drone that fills the whole room. Not at all what is described by the diplomats and family members. I hope they can get to the bottom of this and I hope that more information is made public.

Can something activate the perception of the sound in the brain, maybe a high intensity ultrasound or another frequency that with enough intensity would activate the hairs in the inner ear or the nerve signals. For something to cause brain damage through the skin and skull bone it would have to be pretty intense I would imagine...

  I believe they have an audio recording of the sound, suggesting it's not purely a brain activation/attack. https://youtu.be/HcI7yYK_6Z8 https://youtu.be/HcI7yYK_6Z8

  Yes, microwave energy can do pretty much exactly what you're saying, and perhaps other forms of radiation could directly activate nerves as well. It's also possible that if the brain damage includes auditory processing then it could be phantom sounds. It's too many options, too little evidence, but microwaves seem like a good culprit. It doesn't seem too far-fetched that such a system could induce something like a "recording" as well, or that recording could be coincidental. If they had devices in the embassy which required maybe intersecting "beams" of microwaves to power up and transmit, and something went wrong...

  Yeah, the descriptions they offer remind me of the few times I've “heard” meteorites plunging through the atmosphere: https://www.theguardian.com/education/2003/oct/23/research.highereducation1 https://www.theguardian.com/education/2003/oct/23/research.h...

  There is an actual recording of these sounds. Microwaves inducing sounds into a humans perception and at the same time inducing it in recording equipment does not seem plausible. There is also an easy way to test whether the sound is actual sound conducted in air or the effect of microwave exposure: ear plugs.

ultrasound is completely capable of not only affecting brain tissue, but destroying it. as with anything else: it's about the amount of energy you put into it. Focused ultrasound would be completely capable, and share the quality of being perceptable in the targeted region, and absent elsewhere. https://www.fusfoundation.org/diseases-and-conditions/neurological/essential-tremor https://www.fusfoundation.org/diseases-and-conditions/neurol...

  Yes, but at which frequencies, power and more important, acoustic coupling with the skull?

    Check out "parametric speakers". Amazon has an assembled kit for sale: http://amzn.to/2AxtPBS http://amzn.to/2AxtPBS Also, more info from soundlazer.com, here: http://www.soundlazer.com/what-is-a-parametric-speaker/ http://www.soundlazer.com/what-is-a-parametric-speaker/ Also, reminds me of the MacGyver (original) episode "Soft Touch"- where a Columbian drug cartel tortures a federal agent in a garage using high-decibel noise.

  But generating that much energy requires a huge piece of equipment. For example, the unit used for the ablative technique you linked to is quite large and works only at very short distances.

    What about multiple devices where their respective waves converge at a specific point?

Ultrasound does damage brain tissue. It has been studied in China, where evidently it was considered ethical to do so. Search terms: China ultrasound study What this does to the population's average mental ability and sanity is an interesting question. Autism is suspected.
